This example tests the the ECC injection function of the PPU attribute registers which is configured in SRAM.
- Set the correct ECC parity and enable the ECC injection.
- Read the attribute registers (expecting no error)
- Write 1-bit inverted data to one of the attribute registers.
- Read the attribute register (expecting correctable error)
- Write 2-bits inverted data to one of the attribute registers.
- Read the attribute register (expecting non-correctable error)
